The 24-year-old played 20 minutes for Italy on Friday night in their 16-6 World Cup practice match loss against Tonga in North Queensland.
Tedesco was a shock omission from the Australian Kangaroos side but did well to put it behind him in a classy showing for the Azzuri.
He saved a certain Michael Jennings try and made a 40-metre break from the Italy goal line.
“First hit out with the Italian boys, it takes a bit of time for combinations but happy with our team performance against a strong Tongan side,” Tedesco said. Assistant Azzuri coach and former Roosters fullback Anthony Minichiello ensured the new Rooster feels welcomed.
“I’m working with Mini as well here so I’ll do a lot with him at the Roosters as well so the connection is good.” Tedesco said.
Italy will open their Cup Campaign against Ireland in Cairns on October 29.
